Google and Bing boost the file range of sitemaps files

While the 50,000 URL limit has not changed, your Sitemaps file size can now be dependent upon 50MB. 

Google and Bing declared together that they have expanded the file size limit of Sitemaps documents from 10MB to 50MB.

That means the uncompressed version should now be under  50MB, no longer under 10MB.

Fabrice Canel, key program manage at Bing, said, "While most sitemaps are under this 10 MB file limit, nowadays, our frameworks once in a while experience sitemaps surpassing this breaking point. … Most frequently this is brought on when sitemap files list very long URLs or in the event that they have attributes listng long additional URLs (as interchange dialect URLs, Image URLs, and so forth), which blows up the measure of the sitemap file."

The 50,000 URL limit per Sitemaps file has not transformed; you can even now just have up to 50,000 URLs in a solitary Sitemap file. Be that as it may, the file estimate has expanded essentially.
